Description
ADuM1250SRZ-RL7 is Analog Devices’ iCoupler digital isolator: a four-channel (quad) digital isolator that provides galvanic isolation between two sides of a system. It is used to transfer multiple digital signals (e.g., SPI, I2C, UART) across an isolation barrier while keeping the two sides powered independently.
Key points:
- Four independent data channels with isolation between primary and secondary sides
- iCoupler technology for high noise immunity, fast edges, and low power
- Dual supplies required on each side (VDD1 and VDD2) with a high isolation rating (typical 5 kV RMS)
- SRZ indicates the 16-lead SOIC package; RL7 denotes tape-and-reel packaging
Typical applications: microcontroller/peripheral isolation, industrial automation, motor drives, medical devices, and any system needing safe, isolated digital signaling.
In short: a compact, high-speed, four-channel digital isolator that safely bridges two circuits while minimizing ground-loop issues and protecting sensitive logic.
